home:/# vgscan
Reading all physical volumes. This may take a while...
Found volume group "system" using metadata type lvm1
home:/# pvcreate /dev/hdd2
Failed to read existing physical volume '/dev/hdd2'
Physical volume "/dev/hdd2" successfully created
It still says "failed to read" etc. but then says successfully created.
Hmm...
home:/# vgextend system /dev/hdd2
Volume group "system" successfully extended
Ok, looks like it is working ok. Now another problem...
home:/# pvmove
Command not implemented yet.
Ugh...looks like LVM1 had it but LVM2 does not yet. Has this changed since
my version?
LVM version: 1.95.10 (2002-05-31)
Even if pvmove is still nonexistant I guess I can put the new disk in another
VG, create LV's over there, and manually copy the data over.
Thanks for the help!
